422 AM AST TUE MAR 3 2026
DISCUSSION
THE KBDI REMAINS ABOVE CRITICAL FIRE WEATHER THRESHOLDS IN CABO
ROJO AND BELOW THRESHOLDS IN GUANICA AND CAMP SANTIAGO. BREEZY TO
WINDY ESE WINDS WILL CONTINUE UP TO AT 17 TO 25 MPH WITH HIGHER
GUSTS AND SEA BREEZE VARIATIONS, BACKING TO BECOME MORE E TO ENE
LATE TONIGHT INTO TOMORROW. THESE WINDS WILL STEER SHALLOW
POCKETS OF MOISTURE OVER THE REGION, THIS COULD POTENTIALLY BRING
SOME SHOWERS OVER THE MORE VULNERABLE AREAS. HOWEVER, PATCHES OF
DRIER AIR WILL ALSO MOVE OVER THE REGION, PROMPTING A DECREASE IN
RH VALUES TO CRITICAL LEVEL AT TIMES. THIS WILL MAINTAIN A
MODERATE FIRE DANGER RISK, HOWEVER WE WILL CONTINUE MONITORING THE
SITUATION THIS MORNING FOR A POSSIBLE HIGH FIRE DANGER RISK.
